Torus Concave Grating SpectrometersCompact Spectrometer Delivers Low Stray Light and High Throughput Torus is a family of aberration-corrected holographic concave diffraction grating spectrometers that delivers low stray light, high throughput and excellent thermal stability for a wide range of research and OEM applications. Our initial Torus model is a Visible range spectrometer (360-825 nm) whose spectral range and low stray light make it especially useful for measuring color. Its high throughput and great thermal stability make it ideal for demanding applications. Like most Ocean Optics...

Low Stray Light, High Throughput Holographic Concave Grating Design T orus Concave Grating Spectrometers Reflective concave gratings are concave mirrors that disperse light; the concavity of the grating reflects and focuses the light and the grating groove pattern disperses the light. These aberration-corrected concave gratings are known for their low stray light and high efficiency. The toroidal (the radius of curvature in the focusing and dispersion directions are different) grating used in Torus further enhances the aberration correction and efficiency. For our Visible Torus...

Understanding Ocean Optics SpectrometersHelpful Hints in Choosing the Optimum Spectrometer Model Spectroscopy is a technique in which the design criteria exist as a set of trade-offs. The optimal spectrometer for you depends entirely upon the application - and your budget. The design process begins by asking a series of questions: What are you trying to measure? How fast do you need the measurement? Where is the sample? Who will be operating the instrument? Then, there's the most important question of all: Why are you making the measurements? Armed with the answers to those questions, Ocean...

Ocean Optics USB-Series spectrometers are versatile performers for a wide array of applications. Although our flagship USB2000+ and USB4000 spectrometers have comparable electronics and architecture, they do have one very important difference: their linear CCD array detectors. In addition, USB2000+ and USB4000 spectrometers are available in application-ready (preconfigured for specific application types) and build-your-own (user-configured for maximum flexibility) versions. Comparing the USB2000+ and USB4000 Spectrometers The USB2000+ has a 2048-element Sony ILX511B detector and the USB4000...

USB2000+UV-VIS and USB2000+VIS-NIR Application-ready Spectrometers for the UV-VIS and VIS-NIR We offer general-purpose UV-VIS and VIS-NIR spectrometers - where all of the optical bench accessories are already selected - for basic spectroscopy applications such as measuring absorbance in solutions and reflectance of solids. Here are some key features: - Each of the four models has an order-sorting filter and 25 pm slit for optical resolution of ~1.5 nm (FWHM) - The USB2000+UV-VIS covers the 200-850 nm range and the USB2000+VIS-NIR covers 350-1000 nm - Enhanced sensitivity models (ES) have an...

The USB4000-UV-VIS and USB4000-VIS-NIR are reliable, robust spectrometers that have a 3648-element linear CCD array detector for good signal-to-noise performance as well as enhanced electronics for controlling the spectrometer and accessories. Each spectrometer has a 3648-element Toshiba TCD1304AP detector with a multibandpass order-sorting filter and 25 pm slit for optical resolution to ~1.5 nm (FWHM). We also offer enhanced-sensitivity (ES) models -distinguished by more efficient light collection optics. The USB4000-UV-VIS covers the 200-850 nm wavelength range and the USB4000-VIS-NIR...

USB Series Spectrometers Extended Range XR Spectrometers Our XR-Series USB Spectrometers are responsive across a wide spectral range and provide you optical resolution of ~2.0 nm (FWHM) with the convenience of a single, monolithic unit that covers wavelengths from ~200-1025 nm. The XR option is now available for our USB2000+ (USB2000+XR1) and USB4000 (USB4000-XR1) Spectrometers and can be configured into custom systems (specify GRATING_#XR1). The extended-range grating is also available in a portable Jaz Spectrometer configuration (see JAZ-EL200-XR1 in the Jaz section). And for enhanced...
